Overview
The DG419AK-E3 is a single-channel CMOS analog switch manufactured by Vishay Siliconix. It features an SPDT configuration housed in an 8-pin MiniDIP package. The device operates with a single supply voltage ranging from 5V to 44V or dual supplies of ±2.5V to ±22V. Key electrical parameters include a maximum on-resistance of 45Ω, a maximum on-time of 175ns, and a maximum off-time of 145ns. It supports a continuous DC current of 30mA and functions within a temperature range of -55°C to +125°C.
Feature Summary
- CMOS logic compatibility for direct interfacing with TTL and CMOS control signals
- Low power consumption suitable for battery-operated applications
- High input impedance minimizing signal loading effects
Applications
- Signal routing in data acquisition systems
- Multiplexing sensor inputs
- Programmable gain amplifier circuits
Procurement Notes
Verify the specific suffix 'AK' corresponds to the MiniDIP package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the operating environment remains within the specified -55°C to +125°C thermal limits. Cross-reference pinout diagrams to prevent installation errors in existing designs.
Selection Notes
Select this component for applications requiring a single SPDT switch with wide supply voltage flexibility. Compare on-resistance specifications against other DG419 variants if lower resistance is critical. Verify that the MiniDIP package dimensions fit the target PCB layout constraints. Consider thermal dissipation requirements given the high-temperature rating.
Part Context
This part belongs to the Vishay DG419 series of high-speed analog switches. The series includes various configurations such as SPST and SPDT options in different packages. The DG419AK-E3 specifically denotes the single-channel SPDT version in a MiniDIP housing. It shares core switching technology with other members of the family while differing in pin count and physical form factor.
